I'm sure you're already familiar with Anthony Peter Senecal, the former butler to Donald Trump and current "historian" at Trump's Mar-A-Lago club, who was caught posting (now-deleted) racist Facebook rants calling for President Obama to be killed:

If you haven't been following this story, read David Corn's post at Mother Jones. Also read the Daily Beast's follow-up ("Trump’s Butler Hates ‘Negroes,’ Wanted To ‘Carpet Bomb’ Ferguson, Called ‘Killery’ Clinton A ‘C**T’").

But there's one pronouncement in Senecal's tsunami of hate that's confusing some observers -- and I think I can explain it. Here's The Atlantic's David Graham:

Even if the posts have been deleted, Senecal didn’t deny them. In fact, he expanded on them to NBC’s Alex Jaffe:

In intvu w @ajjaffe, Trump's butler calls for Obama to be "hung from the portico of the White Mosque," calls Obama daughters "rent-a-kids"

(What does “rent-a-kids” even mean?)

What does "rent-a-kids" mean in this context? MSNBC's Alex Jaffe and Jane Timm offer an inadequate explanation:

But in a phone interview with NBC News, Senecal stood by his remarks in the Facebook post and went even further, saying the president’s children were “rent-a-kids” because he felt they didn’t look sufficiently like their parents....

Well, I'm sure that's what Senecal believes -- but I'm sure that's not all he believes on the subject. "Rent-a-kids" is a phrase you can find all over the online wingnuttosphere if you know enough to look for it. Here's a comment from a thread about President Obama at AllenBWest.com:

Here's a comment from a thread about Malia Obama at a site called The Political Insider:

Here's a series of comments from another Political Insider thread:

Documents Surface Proving That Michelle Obama Never Gave Birth To Malia And Sasha

Reporters have long been suspicious of the lack of pictures of First Daughters Malia and Sasha Obama. We know that the Obamas like to keep their daughters out of the spotlight, but some are starting to suspect that photographs of the girls’ childhood may not exist at all.

Now, rumors suggest that the girls may have been adopted from Morocco. In fact, there is very little evidence of their background. Birth records for both girls yield no results.

Ancestry.com and GenealogyBank.com have no records of Malia and Sasha existing at all.

And many are suspicious that they’ve never seen a photo of Michelle pregnant or holding a newborn baby.

What do you think? Are Malia and Sasha truly the biological children of Barack and Michelle Obama?

The One Political Plaza page goes on to add:

It's a fact....you just can't give birth with this equipment!

Is Michael really fooling anyone?

So that's what much of Wingnut America believes: that Michelle Obama is actually a man named Michael. And I'm sure that's what Senecal believes as well. (We already know that many right-wingers, including World Net Daily's Jerome Corsi and former PUMA Obamaphobe Kevin DuJan, think the president has had many relationships and liaisons with men, including Kal Penn and Reggie Love, not to mention a Pakistani roommate whom Obama is said to have married in his youth, using a ring inscribed "There Is No God but Allah," which he also used in his marriage to Michelle -- or should I say "Michael"???)

By the way, that doctored photo of Michelle Obama in a teal dress also shows up on the Facebook page of Robert Morrow, the half-insane Obama- and Clinton-hater (and current chair of the Republican Party in Travis County, Texas) who co-authored a book with Trump pal Roger Stone called The Clintons' War on Women. Here's the post, one of many repulsive Morrow posts collected by Media Matters:

Here's what I want to know: When is the "respectable" political world going to recognize what a cesspool of hate and delusion conservatism has become in America?
